NOC Anatomy Exam 4 with all Correct & 100% Verified
Answers |Latest Update |Already Graded A+
Plasma ✔Correct Answer-Liquid portion of blood, made mostly of water, proteins, nutrients,
hormones and wastes
Formed Elements of Blood ✔Correct Answer-erythrocytes, leukocytes, platelets
blood serum ✔Correct Answer-plasma minus its clotting factors
Albumin ✔Correct Answer-Most abundant plasma protein, maintains osmotic pressure.
Globulins ✔Correct Answer-Plasma proteins involved in transport and immunity.
Fibrinogen ✔Correct Answer-plasma protein that is converted to fibrin in the clotting process
Hematocrit ✔Correct Answer-percentage of blood volume occupied by red blood cells
hematopoietic tissue ✔Correct Answer-Tissue responsible for blood cell formation; red bone
marrow
Hematopoiesis ✔Correct Answer-formation of blood cells
Erythropoiesis ✔Correct Answer-formation of red blood cells
Granulocytes ✔Correct Answer-A group of leukocytes containing granules in their cytoplasm;
neutrophils, eosinophils, basophils.
Agranulocytes ✔Correct Answer-A group of leukocytes without granules in their nuclei;
lymphocytes, monocytes.
Agglutination ✔Correct Answer-Clumping of microorganisms or blood cells, typically due to
an antigen-antibody interaction.
Coagulation ✔Correct Answer-process of blood clotting
Hemostasis ✔Correct Answer-stoppage of bleeding
Functions of the circulatory system ✔Correct Answer-transport, protection, regulation
Major components of the circulatory system ✔Correct Answer-heart, blood vessels, blood
, Describe the components and physical properties of blood ✔Correct Answer-Plasma (55%)
formed elements (45%): RBC, WBC, and platelets.
Physical Properties:
Viscosity- thicker than water due to cells and proteins
Temp- Slightly warmer than body temp
pH- alkaline
Volume- males: 5-6 L Female: 4-5 L
composition of blood plasma ✔Correct Answer-- water: 92%
- proteins: 7%
- solutes: 1%
Describe the morphology (structure) of erythrocytes and how it relates to their function
✔Correct Answer-biconcave disc, no nucleus or organelles flexible membrane, packed with
hemoglobin. How it supports function: Biconcave shape → increases surface area for rapid gas
exchange. Thin cell → short diffusion distance for O₂ and CO₂. Lack of nucleus/organelles →
more room for hemoglobin, maximizing oxygen-carrying capacity. Flexibility → allows RBCs to
squeeze through tiny capillaries
Describe the structure and function of hemoglobin ✔Correct Answer-consists of 4 protein
chains - globins; 2 alphas and 2 betas, carries carbon dioxide. 4 heme groups; binds oxygen to
ferrous ion at its center
Explain erythropoiesis ✔Correct Answer-Occurs in the bone marrow, maintains steady state of
erythrocytes in the body, begins with pluripotential or hematopoietic stem cell which becomes
myeloid stem cell, myeloid stem cell then commits to erythroid progenitor cell
Takes 3-5 days
identify the life span of red blood cells and what organs kill them ✔Correct Answer-120 days;
the spleen and liver
Explain the difference in the surface antigens in the ABO, Rh blood typing system ✔Correct
Answer-Type A: A antigens; anti-B antibodies. Type B: B antigens; Anti- A antibodies. Type AB: A
and B antigens. Type O: no antigens; anti-A and Anti-B antibodies. Rh-positive: D antigen
presents. Rh-Negative: D antigen absent
function of 5 leukocytes ✔Correct Answer-Neutrophils: Rapid response that phagocytize
bacteria. Eosinophils: Combat parasites and help control allergic reactions. Basophils: Release
Histamine and Heparin. Lymphocytes: Specific immunity. Monocyte: Become macrophages in
tissues; powerful phagocytes
white blood cell formation ✔Correct Answer-Occurs in red bone marrow, hemopoietic stem
cell - myeloid line- lymphoid line.
